FAQ: Sand & Gravel
Q: When would I use sand vs gravel in building stuff? A: Sand's great for masonry work, like with cement, or for leveling things out. Gravel, on the other hand, is a champ for driveways, helping with drainage, or serving as the foundation for roads.
Q: Do I need washed or unwashed sand for my project? A: Well, if you're looking to mix with cement, washed sand's your best friend. But if you just need to level or fill something, unwashed should do the trick.
Q: How heavy is a big pile of sand or gravel? A: A cubic yard of this stuff usually weighs somewhere between 1.25 to 1.5 tons. And if you're curious, a ton is about 2,000 pounds. But keep in mind, it can change a bit depending on whether you're talking rock vs. sand, and if it's had a recent rain shower or not.
Q: Any tips for figuring out how much material I need? A: Remember this little tidbit: 1 cubic yard can roughly cover about 100 square feet if you spread it 2-3 inches deep. So, measure your space, divide by 100, and that should get you in the ballpark.
Q: How quickly can I get a truck delivery of the sand and gravel materials I order? A: You're usually looking at about a day or two, but it might change based on how much you need and where you're located. If open and available we can deliver the same day, if you job requires it.
Q: Does ContractorLOADS deliver on the weekends, holidays and nights? A: Yes we can deliver on Saturdays when arranged in advanced for a slightly higher service charge. ContractorLOADS is not open on major holidays. And ContractorLOADS does offer night delivered of sand and gravel for construction jobs that work at nights. This will have to be arranged in advance but it is possible.
Q: What are the main differences between sand and gravel? A: Sand particles are typically smaller and come from pulverized rock or minerals. Gravel, on the other hand, consists of larger particles, often rounded, and is commonly used for driveways and drainage.
Q: What are the primary uses of sand in construction? A: Sand is versatile. It's used in concrete mixing, masonry work, plastering, and even as a base for pavers. It also plays a role in landscaping, particularly for leveling purposes.
Q: How can I determine the right type of gravel for my project? A: It depends on the project. For driveways, a compactable gravel like Class 2 road base is ideal. For decorative purposes, pea gravel or river rock might be more appropriate. Discussing your project's specifics with a material expert can be beneficial.
Q: How do I prevent weeds from growing through my gravel path or driveway? A: Before laying gravel, it's advisable to place a weed barrier or landscaping fabric. This can inhibit weed growth, though occasional maintenance might still be necessary.
Q: Can sand be used for pet areas, like a sandbox or a cat litter area? A: Yes, play sand is often used for children's sandboxes and can be used for pet areas as well. Ensure it's free from chemicals and contaminants before using.
Q: What is the difference between "washed sand vs unwashed screened dry sand"? A: Washed sand has been screened at 5/32" (finer) or 3/16" (corser) and cleaned of silt, clay, and other impurities, making it a better choice for projects like concrete mixing where purity is crucial.
Q: How can I ensure my gravel driveway remains even over time? A: Regular maintenance, like raking to spread the gravel evenly and adding a new layer as needed, can help maintain an even surface.
Q: How often should I replenish or top up my gravel areas? A: Depending on the traffic and wear and tare, a gravel area might need replenishing every 1-2 years.
Q: I'm planning a garden pathway. Would sand or gravel be better? A: Both can work! Gravel provides a firmer, crunchier path and offers excellent drainage. Sand gives a softer look and feel. Your choice depends on the aesthetic and functionality you desire.
Q: How do I calculate the amount of sand or gravel needed for my project? A: A general rule is that 1 cubic yard can cover 100 square feet to a depth of 2-3 inches.
Q: How much does a cubic yard of sand or gravel weigh? A: Typically, a cubic yard of sand and gravel weighs between 1.25 to 1.5 tons, or 2,500 to 3,000 pounds.
Q: What's the difference between pea gravel and decomposed granite? A: Pea gravel consists of small, rounded stones, often used for decorative purposes. Decomposed granite is a granular material resulting from granite weathering.
Q: Do you recommend a specific gravel size for drainage solutions? A: This depends on application use. But as a general rule drainage, slightly larger gravels, often between 3/4", 1" inch and 1.5" inch, are ideal.
Q: Contractors need high quality sand and gravel materials that meet specs? A: The response outlines 11 testing standards including Aggregate Gradation, Specific Gravity and Absorption, Los Angeles Abrasion Test, Soundness Test, California Bearing Ratio (CBR), Unconfined Compressive Strength, Sieve Analysis, Particle Shape and Surface Texture, Flakiness and Elongation Index, Sulfate Soundness Test, and Alkali-Silica Reactivity (ASR) Test.
FAQ: Homeowners
Q: I'm new to home improvement. How do I know which material is right for my project? A: We are happy to make recommendations, but its best you speak to a qualified landscaper or contractor.
Q: How can I calculate the amount of material I need for my project? A: A simple formula is to divide the area (in square feet) by 100 to estimate the number of cubic yards required, assuming a depth of 2-3 inches.
Q: Using the formula, how many cubic yards would I need for a 500 sq. ft. area? A: For a 2-3 inch depth, you'd need approximately 5 cubic yards. (500 sq. ft. ÷ 100 = 5 cubic yards).
Q: Can I mix different materials, like sand and decomposed granite, for my project? A: Yes, depending on the project, mixing materials can provide both functional and aesthetic benefits. It's essential to consult with experts landscaper or contractor before mixing to ensure compatibility.
Q: Is there any prep work I need to do on the site before the material is spread? A: It's recommended to clear the area of any debris, ensure it's level, and, for some projects, lay a weed barrier or fabric beneath the material.
Q: How long will the materials last? Do I need to replenish them periodically? A: The longevity depends on its use. While gravel driveways might require occasional replenishment due to displacement, a decomposed granite pathway can last years with proper maintenance.
Q: Do the colors of materials like decomposed granite or gravel fade over time? A: Natural materials might experience slight fading over time due to weather and wear. Sealing or using a stabilizer can help retain the color.
Q: How do I maintain the appearance and function of the materials once laid? A: Regularly removing debris, occasional raking or leveling for even distribution, and replenishing material as needed can maintain both appearance and function.
Q: Can these materials be laid in areas with heavy foot or vehicle traffic? A: Absolutely. Some materials, like compacted gravel, are designed to withstand heavy traffic, making them perfect for driveways and high-footfall paths.
